Preliminary Report - Temperature Effects In MTC-Type Ferrite Cores

Abstract:

The curves given in this note show the effect of temperature on ferrite core operation. For a particular driving current amplitude, there is a point (or range) in temperature beyond which core operation degenerates rapidly, for the MTC cores used in this test, the temperature coefficient is about 1 mv/deggee C; the Critical Point at 1.00 amp is 40 degrees C; at 0.95 amp 50 degrees C; at 0.90 amp 60 degrees; at 0.80 amp 70 degrees C.
